Adult: Once the adult house fly hatches from the pupal stage, it has an approximate life span of 15 to 30 days. Females are able to start producing eggs after two days of life and will continue to lay eggs for about a month. Female house flys are usually larger than the males.
The fact is, fish flies exist solely to mate. Alas for the fly, the lifespan of a single adult specimen is anywhere from 30 minutes to one day, depending on the species. Dead or alive, they stick to decks and houses and patio furniture like Velcro. Many people power-wash the fish flies off their houses and storefronts.
